Abstract: A system for modifying ice adhesion strength of ice adhered to an object comprises a composite coating containing wire electrodes covering the surface to be protected. In one embodiment, a composite coating contains electrode wires and insulator fibers. The composite coating is applied to the surface of an object on which the ice adhesion strength is to be modified. The electrode wires are connected to a do bias source, and they function as cathodes and anodes alternately.      The source generates a DC bias to an interface between the ice and the surface when the ice completes the circuit between anode and cathode wires. In another embodiment, a wire mesh is disposed on an electrically conductive surface of the object an opposing DC biases are applied to the mesh and the surface. In another embodiment, the coating has anode and cathode wires woven by insulator fibers as a composite cloth applied to the surface to protect the surface from ice.

Patent CA-2428172-A1 (CA)
Inventor: PUTNAM MARTIN A
IPC: H01S3/1055
Filed: 2001-10-22
Abstract: A tunable Raman (40) laser and amplifier include a pair of tunable optical units (42, 44) optically connected by a length of optical fiber (46) having an associated Raman gain. The tunable optical units (42, 44) tune respective optical waveguides (50, 60), each of which includes an inner core (56) disposed within an outer cladding (58). A plurality of Bragg gratings (51-54, 61-64) is written in each core (56) of the waveguides (50, 60). The reflexion wavelengths of each Bragg grating (51-54) of the input waveguide (50) is the same as the reflection wavelength of a matched grating of the output waveguide (60), to thereby form a plurality of cascaded resonance cavities. Each resonance cavity has a reflecting wavelength equal to the center wavelength of successive Stokes orders associated with optical fiber. The Bragg gratings (51- 54, 61-64) of each waveguide (50, 60) are written into a corresponding stepped region ground into the outer cladding (58) of the waveguides (50, 60). The tuning (e.g., compression) of the waveguides proportionally changes the reflexion wavelengths of the gratins, and thereby proportionally changes the center wavelength of each resonance cavity. This method of proportionally tuning each matched pair of Bragg gratings enables the Raman laser to be tunable over an extended wavelength range.
